Gas and condensate





Project details

Touat gathers together ten gas fields in the Sahara Desert, near the city of Adrar in Algeria, as a single networked facility. The envisaged development project, consisting of infrastructure, production wells and a central processing facility, covers more than 1,300 km².

Neptune joined forces with Sonatrach in 2002 to explore and produce gas fields in the Touat area. Exploration and appraisal activities between 2003 and 2007 drilled seven wells and confirmed enough natural gas to plan development.

The development plan was approved in 2009. In 2010, the companies set up a joint venture, Groupement TouatGaz (GTG), which became the operator of the development and production operations. The plan estimates 4.5 billion m3 gas production and 630 kboe condensate annually.

The project consists of production wells, pipeline infrastructure, and a central processing facility capable of 75 kboepd, with an export pipeline into the Algeria gathering system. The field will connect to a Sonatrach pipeline transporting gas from southwest Algeria 800 km north to Hassi R’Mel.

Development works have included drilling 41 production wells, building living quarters, a road, an aircraft runway, a gathering network and gas treatment facilities.

Project status

As at 21/03/19

Gas was received into the plant on 19 February 2019, firing up the power turbines and providing power.

Construction of the gathering network and gas treatment facilities is at 97.3%. Commissioning of the CPF (Central Processing Facilities) has reached 71.5%.

Projected first gas H1 2019


The project is led by Groupement Touat Gaz (GTG Partners), consisting of Neptune Energy Touat (65%) and Sonatrach (35%). Within Neptune Energy Touat, ENGIE holds 46% and Neptune 54%.
